Inventor: HAMAEKERS ARNO DIPL ING
IPC: F16F13/00
Filed: 1989-11-02
Abstract: A hydraulically damped rubber cartridge spring incorporates two chamber pairs (4, 6; 5, 7) isolated from one another by a wall (8 ). The chambers are located at a distance from one another in the direction of the introduced vibrations. The chambers of each chamber pair are connected by damping orifices (9, 10) of a channel-like configuration. The damping orifices (9, 10) are so dimensioned and coordinated with the bulge elasticity of the corresponding walls (11) of the bilaternally adjoining chambers, that the contained liquid mass enters into a resonant motion if the vibrations introduced by the spring's operation differ from one another in frequency. The dividing wall (8) contacts the external sleeve (1) loosely when vibrations are not introduced, and at the same time is resiliently deformed toward the internal tube (2) by the external sleeve (1).

Patent DE-4029141-A1 (DE)
Inventor: BOEHME KLAUS DIPL ING
IPC: G01R27/08
Filed: 1990-09-11
Abstract: In a process for finding the short-circuit impedance of an electric power supply system to be monitored, coefficients of a system matrix Xi or a system matrix Xu1 of a preselected model of an electric power supply system is calculated taking account of the mains frequency of the system to be monitored and the preselected time sequence of scanned values of a measurement value proportional to the current and voltage in the system. Starting with preselected parameter vectors beta i(O) or  beta u1(O), error vectors at a predetermined smallest error vector are found with the actual scanned values of the measurements and the actual system matrix Xi or Xu1 by recursive estimation and the short-circuit impedance is determined therefrom. In order to avoid errors through the effect of an arc in finding the short-circuit impedance, in the process of the invention the system matrix Xu1 is calculated by including and taking account of the actual sign of the scanned value (yi(k)) of one measurement; in addition, an additional component taking account of a short circuit arc is included in calculating the parameter vector  beta u1.
